Application of Phosphating solution treatment of non-woven fabrics
The application of phosphating filter paper in various automotive production line phosphating equipment systems, such as: fk phosphating filter press, mcf series belt filter, alsi full filtration filter press, (ps) filtration system, etc;
The purpose and reasons for using Phosphating solution treatment of non-woven fabrics
The purpose of phosphating treatment is to improve the adhesion and corrosion resistance of the coating. Currently, many automotive production processes use new imported automatic dehydration phosphating slag removal machines. In recent years, with the development of China's economy, the treatment technology of metal materials has undergone rapid development. Phosphating treatment technology, as a very mature technology, can significantly improve the adhesion and corrosion resistance of coatings by phosphating the surface of metal materials before painting. Phosphating treatment technology has also been widely popularized in various industries, especially in the automotive industry, The phosphating film, as the bottom layer of electrophoretic painting, has been almost 100% applied.
Along with the process of phosphating treatment, the generation of phosphating sediment is inevitable. If excessive phosphating slag is not removed from the tank solution in a timely manner, it will not only pollute the phosphating solution and shorten its service life, but also adhere to the metal surface, affecting the quality of the phosphating film and the overall coating quality of the components; For the spraying system, excessive phosphating slag can easily cause nozzle blockage and pipeline blockage, reduce the heat transfer efficiency of the heat exchange system, and cause the entire production line to be unable to operate normally. Therefore, feasible measures must be taken to control the phosphating slag content in the tank liquid within a certain range. As a result, various phosphating slag removal systems (devices) have emerged.
Due to the use of phosphating filter paper in relevant phosphating slag removal systems (devices), there is a growing demand for phosphating filter paper. The commonly used fibers in the production of phosphating filter paper include wood fibers, chemical fibers, and glass fibers. The types of filter paper are developed based on the characteristics of the filter machinery used in industrial production and the requirements for acid and alkali resistance in the production products. The model and specifications of the filter paper are selected based on the molecular fineness of the substances required in the production process settings of the user unit.
Phosphate solution filter paper is generally used for phosphate solution belt filters, which can be further divided into flat mesh paper belt filters, drum paper belt filters, belt filter presses, etc
The commonly used specifications for Phosphating solution treatment of non-woven fabrics are as follows：
650MM*50M /650MM*25M 500MM*50M /500MM*25M
